Description

Technical Field

[0001] The utility model relates to the technical field of transshipment and transportation, in particular to a navigation mark transshipment flat car. Background Art

[0002] Navigation marks (such as buoys / light buoys) are indispensable aids to maritime traffic. Their good maintenance status is directly related to the safety and efficiency of navigation. The clear marking and good condition of the buoys can provide accurate navigation information for ships, reduce the occurrence of collision accidents, and ensure the safety of maritime navigation and water construction. Since buoys are exposed to seawater for a long time and are affected by various natural factors such as seawater erosion, ultraviolet radiation, and tidal effects, their maintenance is extremely important, and often require anti-corrosion treatment and paint coating on their surfaces.

[0003] Since navigation marks (especially large buoys) are large in size and heavy in weight, traditional methods of transporting navigation marks often involve lifting or towing them to rust removal and maintenance workshops or spray paint rooms. This is not convenient for subsequent cleaning, rust removal or spray paint operations on the navigation marks, and may also cause damage to the navigation marks themselves, increasing maintenance costs.

[0004] Therefore, in view of this, the inventor proposes a navigation mark transfer flat car to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a navigation mark transfer flat car to solve the problem that the traditional navigation mark is inconvenient to transfer and spray and paint.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A navigation mark transfer flat car, comprising a car body, a front jacking structure and a rear jacking mechanism, wherein the front jacking structure and the rear jacking mechanism are respectively arranged on the upper surface of the car body along the length direction of the car body, and the front jacking structure and the rear jacking mechanism are used to support the navigation mark;

[0008] A traveling mechanism is disposed on the lower surface of the vehicle body, and a traveling oil motor is disposed on one side of the traveling mechanism, and the traveling oil motor is used to drive the traveling mechanism to rotate;

[0009] It also includes a driving system, which is installed on the vehicle body. The front lifting structure, the rear lifting mechanism and the travel oil motor are all connected to the driving system, and the driving system is used to drive the front lifting structure and the rear lifting mechanism to rise or fall.

[0010] According to the above technical solution, the front jacking structure and the rear jacking mechanism are respectively arranged on the upper surface of the vehicle body. These two mechanisms are used to stably support the navigation mark. When the navigation mark needs to be sprayed, the drive system starts, and the front jacking structure and the rear jacking mechanism are controlled to rise synchronously, and the navigation mark is lifted from the supporting surface on the vehicle body; the walking mechanism is used to realize the movement of the flat car; the drive system is the power and control center of the entire flat car, which is responsible for providing power to the front jacking structure, the rear jacking mechanism and the walking oil motor, and controlling their operating status. The navigation mark transfer flat car can quickly and stably transfer the navigation mark from one place to another, reducing the trouble and time cost of manual handling.

[0011] Furthermore, it also includes a slewing mechanism, which is installed on the upper surface of the vehicle body, and is arranged between the front lifting structure and the rear lifting mechanism, and is used to drive the navigation mark to rotate.

[0012] Further, the slewing mechanism comprises a main slewing mechanism and a slave slewing mechanism, and along the width direction of the vehicle body, the main slewing mechanism and the slave slewing mechanism are respectively located on both sides of the vehicle body;

[0013] When the navigation mark is installed on the front lifting structure and the rear lifting mechanism, and the front lifting structure and the rear lifting mechanism are both in a descending state, the main rotating mechanism and the slave rotating mechanism are respectively in contact with the navigation mark.

[0014] Further, the main rotary mechanism comprises a rotary oil motor and a rotary unit, and the rotary oil motor is installed on one side of the rotary unit;

[0015] The slave slewing mechanism is a slewing unit.

[0016] Furthermore, the swivel unit includes a swivel seat, a first rotating shaft rotatably connected to the swivel seat, and a plurality of rotating wheels coaxially connected to the first rotating shaft, and the swivel seat is detachably mounted on the upper surface of the vehicle body.

[0017] According to the above technical scheme, the navigation mark is erected on the front lifting structure and the rear lifting mechanism. When the front lifting structure and the rear lifting mechanism are in a descending state, the bottom of the navigation mark is in contact with the rotating wheels of the main slewing mechanism and the slave slewing mechanism; the drive system is started, the rotating oil motor starts to run, and the power generated by the rotating oil motor is transmitted to the slewing unit of the main slewing mechanism; since the slave slewing mechanism does not have an independent rotating oil motor, it mainly realizes the purpose of synchronous rotation. With the continuous operation of the rotating oil motor, the rotating wheel on the first rotating shaft is driven to contact the bottom of the navigation mark and transmit the rotational force, so that the navigation mark begins to rotate around its central axis, and the slewing unit of the slave slewing mechanism also rotates synchronously, and together with the main slewing mechanism, provides stable rotation support for the navigation mark.

[0018] Furthermore, the front lifting structure is a double-support structure, and the front lifting structure includes two front lifting cylinders, and the front lifting cylinders can be raised or lowered at the same time; along the width direction of the vehicle body, the two front lifting cylinders are symmetrically arranged on both sides of the vehicle body;

[0019] The rear lifting mechanism is a rear lifting cylinder, which can rise or fall; along the width direction of the vehicle body, the rear lifting cylinder is arranged in the middle position of the vehicle body.

[0020] According to the above technical solution, the front lifting structure includes two front lifting cylinders, which are symmetrically arranged on both sides of the vehicle body along the width direction of the vehicle body. This layout helps to provide stable supporting force and ensure the balance of the navigation mark during the lifting process; when the navigation mark needs to be raised, the drive system starts to provide power to the two front lifting cylinders, so that the hydraulic oil in the cylinders is pressurized, pushing the piston to move upward, thereby driving the top of the front lifting cylinder (that is, the part in contact with the navigation mark) to rise.

[0021] Furthermore, the walking mechanism includes two walking units, and the walking unit includes a second rotating shaft and a caster coaxially connected to the second rotating shaft.

[0022] According to the above technical solution, the second rotating shaft serves as the support and transmission component of the caster. The second rotating shaft is responsible for transmitting power (driven by the walking oil motor) to the caster so that it can rotate. The movement of the device is achieved through its rotation. When the casters start to rotate, they generate friction with the ground, pushing the entire device forward or backward.

[0023] Further, the driving system comprises a motor oil pump group, an oil tank and a manual valve group, and the motor oil pump group is connected to the manual valve group;

[0024] High-pressure oil pipes are connected between the motor oil pump group and the oil tank, between the oil tank and the rotating oil motor, between the oil tank and the traveling oil motor, between the motor oil pump group and the rotating oil motor, and between the motor oil pump group and the traveling oil motor. The motor oil pump group includes a motor and an oil pump, and the motor is used to drive the oil pump to rotate.

[0025] Furthermore, four lifting rings are provided on the navigation mark, wherein the four lifting rings are symmetrically arranged in pairs; support blocks are provided on the two front lifting cylinders, and the support blocks are rotatably installed on the top of the front lifting cylinders, and the two support blocks can be inserted into the two lifting rings symmetrically arranged therein.

[0026] Furthermore, the number of the front lifting structures is one or two, and the number of the front lifting structures is consistent with the number of the slewing mechanisms.

[0027] According to the above technical solution, by installing one or two front lifting mechanisms on the vehicle body, it is convenient to support navigation marks of different sizes, has strong adaptability and is practical.

[0028] Beneficial effects of the utility model:

[0029] A front lifting structure and a rear lifting mechanism are provided to lift the navigation mark and separate it from the contact surface of the rotating wheel. During the process of spraying paint on the navigation mark, the problem of the rotating wheel scratching the painted paint during rotation is avoided. Lifting the navigation mark can ensure that the paint covers the surface of the navigation mark evenly and completely, thereby improving the quality and aesthetics of the sprayed paint.

[0030] The automated lifting and rotating mechanism reduces the need for direct manual operation, reduces the risk of safety accidents caused by human factors, and improves the safety of the operation process; the equipped slewing mechanism can drive the navigation mark to rotate, making the spraying operation more uniform, improving the spraying quality and efficiency, and reducing rework and waste caused by uneven spraying.

[0042] Embodiment 1

[0043] This embodiment proposes a navigation mark transfer flat car, such as Figures 1 to 7 As shown, the vehicle body 1, the front lifting structure 2 and the rear lifting mechanism 3 are arranged along the length direction of the vehicle body 1 (i.e. Figure 1 In the horizontal direction), the front lifting structure 2 and the rear lifting mechanism 3 are respectively installed on the upper surface of the vehicle body 1. When the navigation mark 4 is placed on the vehicle body 1, the front lifting structure 2 and the rear lifting mechanism 3 are used to support the navigation mark 4.

[0044] A traveling mechanism 5 is disposed on the lower surface of the vehicle body 1, and a traveling oil motor 6 is disposed on one side of the traveling mechanism 5, and the traveling oil motor 6 is used to drive the traveling mechanism 5 to rotate;

[0045] It also includes a drive system 7, which is installed on the vehicle body 1. The front lifting structure 2, the rear lifting mechanism 3 and the travel oil motor 6 are all connected to the drive system 7. The drive system 7 is used to drive the front lifting structure 2 and the rear lifting mechanism 3 to rise or fall; the drive system 7 is used to drive the travel oil motor 6 to rotate.

[0046] As a preferred exemplary embodiment, the preferred model of the travel oil motor 6 is ZJM08-0-112mSEZ, the speed range is 0-170r / min, and the rated output torque is 2914N.m.

[0047] According to the above technical scheme, the front lifting structure 2 and the rear lifting mechanism 3 are respectively arranged on the upper surface of the vehicle body 1, and these two mechanisms are used to stably support the navigation mark 4. The drive system 7 is started, and then the front lifting structure 2 and the rear lifting mechanism 3 are controlled to make them rise or fall synchronously, and lift or lower the navigation mark 4 from the vehicle body 1; the walking mechanism 5 is used to realize the movement of the flat car; the drive system 7 is the power and control center of the entire flat car, which is responsible for providing power to the front lifting structure 2, the rear lifting mechanism 3 and the walking oil motor 6, and controlling their operating status; the flat car can quickly and stably transport the navigation mark 4 from one place to another, reducing the trouble and time cost of manual handling.

[0048] As a preferred exemplary embodiment, the drive system 7 includes a motor oil pump group 71, an oil tank 72 and a manual valve group 73, and the motor oil pump group 71 is connected to the manual valve group 73; high-pressure oil pipes are connected between the motor oil pump group 71 and the oil tank 72, between the oil tank 72 and the rotating oil motor 811, between the oil tank 72 and the traveling oil motor 6, between the motor oil pump group 71 and the rotating oil motor 811, and between the motor oil pump group 71 and the traveling oil motor 6. Preferably, the manual valve group 73 adopts a collection of multiple manual valves, including multiple valves. Further, the motor oil pump group 71 includes a motor and an oil pump (not shown), and the motor is used to drive the oil pump to rotate. The oil pump is connected to the motor. When the motor rotates, the pump body of the oil pump will also rotate. The oil pump contains multiple working chambers and corresponding sealing structures. The rotation generates oil suction and oil discharge actions. When the motor starts, it will generate a rotational force and transmit the rotational force to the oil pump. After the oil pump receives the rotational force, the pump body inside it begins to rotate, thereby driving the oil to flow in the pump body. During the rotation of the oil pump, the volume of its working chamber will change. When the volume of the working chamber increases, a low-pressure area is formed, and the oil in the oil tank 72 is sucked into the working chamber; when the volume of the working chamber decreases, the oil is compressed and discharged from the working chamber. Through the continuous rotation of the oil pump, the oil is continuously sucked in and discharged from the oil tank 72, forming a continuous oil flow. The discharged oil is transported to actuators such as the rotating oil motor 811 and the traveling oil motor 6 through a high-pressure oil pipe. Inside the actuator, the pressure energy of the oil can be converted into mechanical energy, thereby driving the rotating oil motor 811 to rotate or the traveling oil motor 6 to travel. The working state (such as speed, flow rate, etc.) of the motor oil pump group 71 can be controlled by the manual valve group 73, and the flow direction and pressure of the oil can also be adjusted to meet the needs under different working conditions.

[0049] In the entire drive system 7, the motor oil pump group 71, the oil tank 72, the manual valve group 73, the rotating oil motor 811 and the travel oil motor 6 and other components work together to realize the functions of moving the beacon 4 transfer flat car and rotating the slewing mechanism 8.

[0050] As a preferred embodiment, Figure 3 As shown, four lifting rings 41 are provided on the navigation mark 4, wherein the four lifting rings 41 are symmetrically arranged in pairs; support blocks 211 are provided on the two front lifting cylinders 21, and the support blocks 211 are rotatably installed on the top of the front lifting cylinders 21, and the two support blocks 211 can be inserted into the two lifting rings 41 symmetrically arranged therein, and by rotating the support blocks 211, its angle can be conveniently adjusted to make it better aligned with the lifting rings 41; when the navigation mark 4 is ready to be lifted, ensure that the two support blocks 211 are inserted into the two symmetrical lifting rings 41 on the navigation mark 4, and then the support blocks 211 and the lifting rings 41 are locked and fixed to improve the safety of the lifting operation.

[0051] As a preferred embodiment, the present embodiment further includes a slewing mechanism 8, which is mounted on the upper surface of the vehicle body 1 and disposed between the front lifting structure 2 and the rear lifting mechanism 3, and is used to drive the navigation mark 4 to rotate.

[0052] As a preferred embodiment, Figure 1 and Figure 3 As shown, the rotating mechanism 8 includes a main rotating mechanism 81 and a slave rotating mechanism 82. Along the width direction of the vehicle body 1, the main rotating mechanism 81 and the slave rotating mechanism 82 are respectively located on both sides of the vehicle body 1; when the navigation mark 4 is installed on the front lifting structure 2 and the rear lifting mechanism 3, and the front lifting structure 2 and the rear lifting mechanism 3 are both in a descending / retracted state, the main rotating mechanism 81 and the slave rotating mechanism 82 are respectively abutted against the navigation mark 4.

[0053] As a preferred embodiment, the main rotating mechanism 81 includes a rotating oil motor 811 and a rotating unit 812, and the rotating oil motor 811 is installed on one side of the rotating unit 812; the slave rotating mechanism 82 is the rotating unit 812, that is, the difference between the main rotating mechanism 81 and the slave rotating mechanism 82 is that the main rotating mechanism 81 further includes a rotating oil motor 811, and the rotating oil motor 811 is connected to the drive system 7 through a high-pressure oil pipe.

[0054] As a preferred exemplary embodiment, the preferred rotary oil motor 811 model is: 2JQM11-0.63 (displacement: 0.664L / rev, maximum pressure 16Mpa, rated pressure 10Mpa, speed range: 4-200r / min, rated output torque: 983492N.m)

[0055] Furthermore, the swivel unit 812 includes a swivel seat 8121, a first rotating shaft 8122 rotatably connected to the swivel seat 8121, and a plurality of rotating wheels 8123 coaxially connected to the first rotating shaft 8122. The swivel seat 8121 is detachably mounted on the upper surface of the vehicle body 1 by bolts.

[0056] According to the above technical scheme, the navigation mark 4 is set up on the front lifting structure 2 and the rear lifting mechanism 3. When the front lifting structure 2 and the rear lifting mechanism 3 are in the descending state, the bottom of the navigation mark 4 is in contact with the rotating wheels 8123 of the main rotating mechanism 81 and the slave rotating mechanism 82; when it is necessary to spray the shielding position at the bottom of the navigation mark, the drive system 7 is started, and the rotating oil motor 811 starts to operate. The power generated by the rotating oil motor 811 is transmitted to the rotating unit 812 of the main rotating mechanism 81; since the slave rotating mechanism 82 does not have an independent rotating oil motor 811, it mainly realizes the purpose of synchronous rotation. With the continuous operation of the rotating oil motor 811, the rotating wheel 8123 on the first rotating shaft 8122 is driven to contact the bottom of the navigation mark 4 and transmit the rotational force, so that the navigation mark 4 begins to rotate around its central axis, and the rotating unit 812 of the slave rotating mechanism 82 also rotates synchronously, and together with the main rotating mechanism 81, provides stable rotation support for the navigation mark 4.

[0057] As a preferred embodiment, the rotating wheel 8123 adopts a press-fit solid tire. The outer diameter of the press-fit solid tire is 305 mm and the width is 165 mm, which can reduce the working height and the rotation linear speed.

[0058] As a preferred exemplary embodiment, the front jacking structure 2 is a double support structure, and the front jacking structure 2 includes two front jacking cylinders 21, which can rise or fall simultaneously; along the width direction of the vehicle body 1, the two front jacking cylinders 21 are symmetrically arranged on both sides of the vehicle body 1; the rear jacking mechanism 3 is a rear jacking cylinder 31, which can rise or fall; along the width direction of the vehicle body 1, the rear jacking cylinder 31 is arranged in the middle position of the vehicle body 1.

[0059] According to the above technical solution, the front lifting structure 2 includes two front lifting cylinders 21, which are symmetrically arranged on both sides of the vehicle body 1 along the width direction of the vehicle body 1. This layout helps to provide stable supporting force and ensure the balance of the navigation mark 4 during the lifting process; when the navigation mark 4 needs to be lifted, the drive system 7 is started to provide power to the two front lifting cylinders 21, so that the hydraulic oil in the front lifting cylinders 21 is pressurized, pushing the piston (not shown) to move upward, thereby driving the top of the front lifting cylinder 21 (i.e., the part in contact with the navigation mark 4) to rise, and the lifting and lowering of the rear lifting cylinder 31 is the same as the working principle of the front lifting cylinder 21.

[0060] Among them, the preferred model of the rear lifting cylinder 31 is HSGL-01-100 / 55×650-E, and the preferred model of the front lifting cylinder 21 is HSGL-01-80 / 45×650-E.

[0061] The front lifting structure 2 and the rear lifting mechanism 3 are used to lift the navigation mark and separate it from the contact surface of the rotating wheel. During the process of spraying paint on the navigation mark, the problem of the rotating wheel scratching the painted paint during rotation is avoided. Lifting the navigation mark can ensure that the paint is evenly and completely covered on the surface of the navigation mark, thereby improving the quality and aesthetics of the sprayed paint.

[0062] When the navigation mark 4 reaches the required height, the drive system 7 stops providing power to the front lifting cylinder 21 and the rear lifting cylinder 31, the hydraulic oil pressure in the front lifting cylinder 21 and the rear lifting cylinder 31 decreases, the piston stops moving, and the navigation mark 4 remains at the current height; when the navigation mark 4 needs to be lowered, the manual valve group 73 controls the motor oil pump group 71 to return the hydraulic oil to the oil tank 72, and the piston moves downward under its own weight or possible spring force, driving the top of the front lifting cylinder 21 and the rear lifting cylinder 31 to descend, ensuring that the navigation mark 4 lands smoothly on the flat car.

[0063] During the spraying operation, the navigation mark 4 is first rotated 90 degrees, and the area of ​​the navigation mark larger than 90 degrees is sprayed. After the area larger than 90 degrees is sprayed with paint, the navigation mark is rotated 90 degrees in the opposite direction to continue the spraying operation. Finally, the navigation mark 4 is lifted by the front lifting structure 2 and the rear lifting structure 3. After it is lifted to a preset height, the paint is sprayed on the bottom of the navigation mark 4.

[0064] As a preferred embodiment, the walking mechanism 5 includes two walking units 51, which are used to be installed on the double tracks of the workshop. The walking unit 51 includes a second rotating shaft 511 and a caster 512 coaxially connected to the second rotating shaft 511. The second rotating shaft 511 serves as a support and transmission component for the caster 512. The walking oil motor 6 drives the second rotating shaft 511 to rotate, and the rotation of the second rotating shaft 511 drives the caster 512 to rotate, and the movement of the device is achieved through the rotation of the caster 512. When the caster 512 starts to rotate, they generate friction with the track of the workshop, pushing the vehicle body 1 to move forward or backward.
